Startup error

Description

Last versions (from 1.0.0) cannot start and show the following error:

webpack.validateSchema is not a function
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! project@0.1.0 start-js: `react-scripts start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the project@0.1.0 start-js script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

And the following is in the log:

Expected behavior

Everything works like in the previous version (0.9.5).

Actual behavior

It doesn’t work. rm -rf node_modules && npm install doesn’t help. Rollback to the version 0.9.5 helps. Haven’t tried to rollback webpack-dev-server to the first version.

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts (if you haven’t ejected): project@0.1.0 /home/user/src/project/frontend └── react-scripts@1.0.6
2. node -v: v7.10.0
3. npm -v: 4.6.1

Then, specify:

1. Operating system: Linux
